P23G:
The Origin, Evolution, and Fate of Comets: New Results from Rosetta, Other Missions, and Ground-Based Observations I Posters


Submit an Abstract to this Session


Session ID#: 48761

Session Description:
Comets are among the primitive building blocks of the planets, but as they enter into the inner Solar System, they become dynamical bodies, almost transient in nature. Some comets have broken up completely (S/L-9 for example), while others have given up a little of themselves. The recent and up-close study of 67/P Churyumov –Gerassimenko during its 2015 perihelion passage has revealed in close detail the types of changes comets undergo as they are heated by the sun.

This session will cover the dynamical nature of the nucleus and coma of 67P/ and other comets. The session will also include comparisons between the results from Rosetta and other missions to understand how comets evolve through time. Broader topics such as the chemistry of comets and what that reveals about their origin and diversity are also welcome. Both spacecraft and ground-based observations are relevant to this session.
